Yellowing in early flower

[plutiot]

Hi, just wanted to get someones opinion on these leaves, i did give em a sligth ligth burn early veg, they are just now showing signs of flowering, i do not currently ph my water (i will get myself a ph meter soon i hope) they are a bit short, i did some lst on them, i migth have been having my ligth to close.. thanks for any input

There are a lot of possibilities that can cause yellowing. Too much or too little fertilizer. Not stabilizing the pH and allowing it to drift up or down. Lights too close and not using a buffer in the water and a few more. Just guessing is not going to help you because the are many possibilities.

It's important to have an EC or TDS meter to watch the ec or ppm with all the incoming and outgoing liquids. Also having a pH meter will allow one to keep an eye on the pH fluctuations and buffer them when using fertilizers. When the pH rises it will lock out micronutrients and when it drops excess nutrient absorption will burn the roots causing yellowing.

Testing the liquids before and after and testing the discharge will keep you informed on the needs of the plants. Until you have these meters you will be guessing and never really know. So I can say the yellowing is caused by you not having these important meters. They are not expensive and very easy to learn how to use, and worth the money.

1. Pruning is in order to increase airflow.
2. The plants are starting to flower and there is an increased need for nitrogen. That's why the chlorosis.

You should prune everything except the strongest tips, and anything growing on the inside of the plants. You should be able to see the wall clearly through the branches.

I did some lower canopy remoal of those mikro nug-sites, i also removed some yellow/big fan leaves, not to much i think, looks better, i did a weak mikro-nutrient feed, before my next/last feeding, i have probably given them too little fertilizer, but i did so in an attempt to not over feed and interupt my ph too much since i dont have a ph meter (i know its a sin, but i work with what i have for now, ph meter comming soon)

I was thinking maby i should increase my feeding now for the last one, im using general hydroponics trio, maby try giving them one full last feeding? Or would that be foolish? I have given them about half strength everything all the way

have you given it any nitrogen? I do a 20-20-20 half way thru flowering

Well, whatever comes in the general hydroponics trio, ive been a bit cheeky adding a few drops of flat beer in some of my water before watering, but extremly little, i will give them next feeding full strength for this, since its been going so well as it has not much size on the plants, im still happy with how far it has come

Ironically it seems i have given one of my auto flowers too much nitrogen lol, i havent posted much on my auto somangoes, but i will soon! Ive lost a bit on controll of sceduels and documenting, spending too much time just looking at them and contiplating how to improve

I gave them a nice feeding full strength they seemed to love it, few to no new yellow leaves, did a proper prune today, seems to be looking perky!
