| | | Too Much Light?
Hey Fellow Gardeners,
I just purchased a 600w hps lamp and threw my 3 plants uder it. It is about 3' above them and ever since they have been under the new lamp, all of the new growth has been those weird 1 bladed or deformed 2 or 3 bladed leaves. It is on a 12-12 cycle and they were in week 4 of flowering when I put them under the HPS. The buds seem to be growing much faster and look healthy. The shade leaves and new growth in the shade all are normal looking 5 or 7 bladed leaves. Has anyone experienced this? Im not too concerned cuz the bud looks fine. Thanks all.

sound strange - could you post a picture for those plant with some close-up shoots of particular bad looking leaves. surely will help to figure this one out (always post some pictures along with our questions to avoid any confusion and resulting wrong advise  )
but in general, 3' is plenty of room between the bulb and your babies normally - how did the HPS effect the temp in your grow and does your grow has some active ventilation?
and what did you do before that, how did you veg those and for how long? right now i can only bother you with those damn nagging questions as what pH, temp, humidity, fertilizers and so you using...

The plants were vegged under 2 40w full spectrum 40w flouros for 5 weeks after the clones took root. Then the first 4 weeks of flowering were done under CFLs... admittedly too few CFLs. PH is 6.5, doing half strength nutes so nuye burn is not a prob. Will do pics tomorrow.

Usually, as a plant is exposed to the flowering cycle, 12/12, the new growth, other than flowers, produces fewer blades per leaf. If, before flower, the plant's leaves have 7 blades, newer growth will have 5, then 3, then very small bracts at the base of buds. At least this is what I've experienced. It could be dependent upon strain, too, I suppose. But, I could be wrong. GN and some of the rest, would probably be more knowledgeable than I.

Rep Power: 500 | | stress
I have experince this too,in fact now in the cab there are two out of the three doing just that.Two leafts and the bud is fine.Here's a pix of them.I thourght that I was using to much cal-mag late in flowering.They are today 12 weeks flowering.What I'am thinking is from all the posts here and in my post of it,That it's STRESS.My lighting has not changed from the start.I know there's alot aways to stress a plant,I'am learning a couple.You can over nutr and water,fresh air not able,heat,nutr lock out,and changing lights to stronger lighting.As a plant it can take some stress and not show it.When it has more than one thing giving it stress it will show it in alot of ways.Some times the plant will stop growing and start again.Some will do what yours and mine are doing.Growing more leavse on top of the bud,just two leavses.There's many things that cause stress,and that's what I have learned from it,is a combo of things and it's like a heart attack to the plant,it may die or it will live.It will just take longer to finish.Well that's my 2 pennys. PEACE

i've noticed this on mine when going from clf to hps and was advised it happens cuase of the way stronger light and the plants will grow out of it. as the plants were under the clf's the lumens were way lower the the suddan intence light causes them to grow so much fast that the leaves are kind of shocked. kind of like putting a plant that has only been grown indoors the put outdoors in direct sun. if that makes any sense

I agree with Ice, the switch from CFL (weak light) to a 600 HPS (very strong light) may have been too radical and stressed the plants. Radical changes like this could cause hermies but you are probably ok if you are already 4 weeks into flowering. Too late now but maybe a slow migration from the CFL to HPS would cause less stress. Good luck.

I had a hermie my last grow. I was leaving town for a few days and had 3 plants flowering but more still vegging. I decided to leave the flowering one outdoors for the 3 days I was gone. One of the 3 developed buds and balls.

PEACE | toke i think you are correct...i dealt with this before too on my last cycle. i asked my local hydro shop dude about it and he said it is due directly to the stress of a couple different factors. he said one of the main stress factors is lack of light...if some plants get too tall and over grow the light source or are too far on the outskirts of the garden they will start to grow this weird new growth from the tops of buds where something like this shouldnt be happening. i think it can effect your yields as well if you subject your girls to enough stress related issues
