 Can you help me???  Hi guys and gals, my plants are 35 days into flowering, and some of them have turn really yellow (from bottom to top). New leaves start to grow green and two days later they turn yellow. I think it could be Mg, Ca or Fe deficiency (my nutes is Dutch Formula, and I have found out from my grow shop that it has low Mg and Ca)  Also, I have been watering my plants 6 times (all watering during the 12 day hours), and each watering takes 20 minutes to flow and 20 minutes to drain. Is this too many waterings per 12 hours or is it too much time per watering, or am I doing ok about the watering and my problem is from a mineral/nute deficiency? Something else, out of 19 plants, just 4-5 are yellow the rest are green, actually very green ANY HELP IS WELCOME PS: Just in case, I have reduced one watering cycle (from 6 to 5 per day)      |

As I have mentioned above I thought it was overwatering because the yellow leaves are falling when touched Thanks in advance |

Thank you for the link! It is a very interesting! And yes, I have checked the tap water, and it comes with 0.24-0.25 EC (100-125ppm), and I think that this is my problem. The Dutch formula is manufactured based on the Holland tap water (the manufacturer is located in Holland) where the tap water is around 0.60 EC (this is what the distributor told me), approx. 3 times the EC than the one I am using. So the product was thought to be used with water with higher Mg, Ca and Fe concentration than the water I am using On the other hand, the pictures in GP´s Hospital threads for plant abuses, the Stitch´s guide and your link, all show similar symptons for Mg defficiency (but I am not completly sure it is Mg defficiency as in my inexperience I can not see difference in the lack Fe, Ca and N symptons from Mg defficiency) This is my first grow and I wanted to confirm with the experienced members here before buying or adding anything to the rez Once again, thanks |

Try some cal/mag. Many types of filtered or distilled waters are short this, 4ever. It will not hurt and could solve your problems, sweetie.

4evah... you can pinpoint your problem by looking at where the yellow starts and reefering to the link I posted.If it starts at the tips its someting...at the base of the leaves it is another disorder Its complicated but you will work it out with the link I feel sure. Read the whole thing and it should be obvious as to what your problem is Let us know whats up please so we kin get smarter too  |

Do you feed them every time you water them? What is the PH of your water?

Hi Chuckd420, Yes, I do feed them everytime I water them as I am using a flood and drain system. I add the nutes to my rez, and check the Ph to be 5.5 to 5.9, being the sweet spot 5.8, when it gets to 6.0 I correct it again to 5.5 Thanks |

I have read it all, now I am sure it is a Mg def. It is as if the author of the pictures and the description in your link was talking about my plants, lol As JAngel suggested me it will not do wrong to add extra Mg and Ca, I will start tomorrow Regards |

If you can't get the Cal-Mag I think you can subistute Bone meal for Cal and Epsom Salts for the Mag. Hope this Helps Peace
