hey guys one of my plant have a little problem nothing major but the leaves are a little bit droopy she is the only one like this and the other ones looks fine .. they've been burnt a little bit by overfeeding but they're recovering right now they are in their second week of flowering .she looks like she's having heat stress but they are pretty far from the light and the heat in my grow tent is pretty good. I always water every 4 days with a pH of 6.10 with 20% runoff and i feed them once a week with florabloom(0-5-4).(1 teaspoon per gallon) .is the bottom leaves slowly turn yellow cause they need some N? cause some doesent give any N during flowering and some does. i need some help here...!

the last picture is one of my ladies whos the leaves start to turn yellow....hungry?

What medium or soil brand are you growing in?

This is not a problem I have experience with but see online quite often.
I'm speculating: If you are watering every 4 days and feeding 0-5-4 (N-P-K) every week then you are feeding P (Phosphorus) every other watering,
Your problem may be that you are feeding to much P to soon, they need 1/2 doses of P in some cases at the beginning of flowering not before and then full strength P at 4 weeks into flowering.

I would shorten this to every 2 or 3 days by giving a bit less water. You want to go crazy with the water in the last 3 weeks to flush out all the nutrients from the medium. No food.

Don't be shy to pull off those old yellow leaves... It increases the ratio of root to plant.

You could water in a bit of fish fertiliser or emulsion to get the colour back.

yes i agree so example last week i watered once with the feed and four day later i only gave them water only and then the bottom leaves stared turning yellow.. so basically i feed every 2 times i water..but in my next feeding, do you recomend me to go with 1/2 teaspoon instead on 1 ?

ok i will try that so bacically what your saying is watering a lil more often to flush the nutes?
I have some shrimp fertilizer, i can mix that with my water.

If that is the problem, I can't help with the next step. I've never grown in pro mix and would only be guessing. I have to leave that for someone with more experience in that area.

I didn't see that you say, if I understand, water twice then feed once?
It is ok to feed, and water alternately, but don't do watering twice until you start flushing.

Too much P&K too early..

Next run, don't start the bloom nutrient till the 3rd week. You might even then, use it 1:1 with the bloom and go full on bloom nutrient at week 4.

The reduction of N in bloom nutrients, is a mistake for the plants needs in the first 2-3 weeks after the lighting change.

Your problem will do nothing but increase till harvest......you can slow it down by increasing the N by at least a whole point.

Hint: The watering before the light change.....Mix the feed at 1:1 Veg and bloom. Water with this only once till week 3 after the flip.

It'll finish out but, won't reach potentials.....While many say "green to the end" (and I have too...a bit).
Some strains at near harvest finish. Color up with various shades of oranges, reds to purples and yellow will spread in....Don't count on that but, remember it.

Green to the late bloom - that's a better statement.
