Any thoughts?

5 SLH, 3 Humboldt Blue Dreams, 2 Dinafem Cheese

3 gallon grow bags full of ocean forest. Been in the bags/soil for 4 weeks.

Been Feeding ro water w/ 25ml calmag plus, 1 tsp per 5g rapid start, liquid karma every once in a while.

Hoping to transplant into "supersoil" mix that has been "cooking" for past month and a half, and flip em to flower in a couple weeks, just want them to be looking healthy going into bud.

They are under 1500 ACTUAL led watts, Temps 73-78, RH 35-55, SEALED ROOM. No supplemental co2 other than air exchange from going in and out of the room a few times a day. (planning to start supplementing co2 at flip to flower).

First run in a sealed room, First run going for water only (mostly). Past grows I have run PBP line.

Any thoughts on whats going on? Are the just getting hungry? Thanks in advance.

Maybe I should add, fresh growth is yellowing, new leaves look kinda skinny, just the very tips are burned and some leaves have mild twisting as you can see in one of the close ups.

No one has any ideas on the yellowing new growth? Plants growth rates have slowed considerably... I have been watering at 6-6.3. I checked the soil with soil ph meter (probe) and it came in at 7. Im thinking that may be my problem? Last watering I adjusted to 5.7 in hope to compensate?

I don't see much yellowing. New growth is always lighter green than older growth.


Maybe they start to be abit root bound and the growth has slowed down because of this.

4+ weeks in OF. Probably time to feed. Feed lightly and observe. Good luck. -granger

Thanks to both for the feedback. Ill feed tonight and see how they respond.

Just to follow up, I think there were a few things going on. Soil ph had drifted 7.5, I realized my ph meter was no longer working properly (even after calibrating to 7.0) in a side by side with the ph drops. I'm sure that was a huge factor. Also went to transplant a few days ago and the 3g grow bags were full to the max with roots, they definatly needed more room to grow into. Everybody seems to be growing well now, letting them grow into supersoil for a week or so then flipping to flower. Ill post up another pic at the flip. Thanks for the feedback.
