veteran grower with newbie questions.

i haven't grown a plant in over 4 years prob more like 8.i still know a lot about growing but im more interested on multiple peoples views. my question is im about 3-4 weeks into flower on 2 indica plants, how much do u think it would fuck up the flower cycle if i transplant them both into bigger pots?is it worth it ?also if its not what do u recommend i feed them? there already yellowing like mad and its only 3-4 weeks in.. and the soil had fertilzer already in it to begin with.

I wouldn't stress them while flowering or you may get some pollen. I would however give them some food. If you want something you can just get at the local store you might get some peters 10-30-20.

Just as Renfro mentioned; don't transplant them at this point and feed them some...just not too much. A full plant pic may lead to other comments / advice. Good luck.

Should have transplanted before you flipped them. If the stretch is over the roots aren't gonna grow anymore so it's too late really

Transplanting is no problem if done gently, roots grow from beginning to last week or so before finish. I found it adds about a week to the bloom period, and the yellowing will stop, If the reason is mostly root binding. Done it many times, saved a prematurely maturing plant. I've even dropped the plant during repotting (in bloom) through her in with fresh soil and broken expose roots, a week later it was tickety boo right to bloom. No nanners, no probs, just an extra 10 days in bloom. Repotting successfully beats the hell out of leafless sticks with tiny buds on them. Regardless, you never know till you try. I assume you are a soil grower, if so feeding is absolutely the opposite of what you should be doing, and the most common shitty advice on these forums. I assume soil, and thats what my experience is with. More specific description will get you better advice. I am uppotting in bloom right now, Start a lot of regs in the bloom room in 2 gal pots (if I want to run a lot of plants (perpetual grow), then flip the females to larger pots and dump and compost the males. Transplanting in veg is favourable, but you have to determine what is best for you. Don't fear repotting.

Repot them if you want. Its not ideal but it shouldn't bother the plant to much and be beneficial in the long term. I wouldn't be cutting the roots back or loosening them, Just a simple up pot. Maybe a Kelp watering in.

Feeding Nutes is easier. The plants use a lot of N in the stretch. You wont need much to bring the green back and start flowering nutes.

Whatever you choose or not you now have an extended flowering time.
